BANGLADESH COVERS AN AREA OF
147,570 sq km, a little more than the size of Greece. It extends from 20°34N to 26°38N latitude and from 88°01E to 92°41E longitude. Maximum extension is about 440 km in the E-W direction and 760 km in the
Anchorage A: the northernmost anchorage for vessels of more than 10 meters draught.
Anchorage B: in between anchorage “A” and “c”, for vessel’s scheduled to enter the
Anchorage C: the southernmost anchorage for lightering vessels and other not scheduled to enter within 24 hours.
From Anchorage to Jetty Berth need approx 2 hours duly compulsory piloting by Port Pilot. Vessels drawing a draught of fewer than 8.5 m usually approaches to Chittagong outer anchorage directly at any time. Vessels drawing draught between 8.5m to 9.5m also approach to the outer anchorage directly depending on the time of arrival and height of the tide. However, vessels drawing draught over 9.5
m usually wait for the rising tide to approach Chittagong outer anchorage if arrives in the falling tide.
DENSITY OF WATER
The density of water varies at each turn of the tide which is semi-diurnal with prominent diurnal effect. It is therefore advisable that the masters check. That density of water at the CPA outer anchorage.
The weather in Bangladesh is largely governed by the monsoon. The prevailing wind directions are from south to southeast during the month of April
through September. After taking easterly direction for a while, The wind turns to the northerly and northeasterly directions, The latter prevails from November to January. During the month of February and March, winds turn via westerly direction back to the transition periods between monsoon and season in May, October and November, extreme of inclement weather like cyclones often occur with wind velocity in excess
of 30 knots. The waves are generally low showing distinct relation with the wind. The waves period vary between 3-4 seconds of waves of about 0.5 meters and about 6 seconds for waves of 2 meters.
During the months May to October, freshets are expected. Freshets are caused by the normal velocity of flow of EBB tide augmented by
expected when rainfall intensity reaches 200 mm in 24 hours.
LIGHTERING OF CARGO AT CHITTAGONG ANCHORAGE AT MONSOON SEASON
Lightening of cargo at Chittagong outer anchorage becomes relatively more difficult with the onset of monsoon and the period from May to October is considered as the monsoon. At any time within this period, rough sea and inclement weather is a common feature of the weather condition and often the weather condition deteriorates so abruptly that incidents, such as the one under consideration, becomes unavoidable. During this period, lighter vessels fastened alongside mother vessel experience heavy rolling and pitching often causing hard scarping, bendings and indentations to the mother vessels railing and hull. This is despite the fact that generally, the lighter vessel has fendering arrangements consisting of old mooring ropes wrapped around wooden spars often used or second-hand tires from automobiles are also used as fenders. Insofar as damages to mother vessel are concerned, top shell plate of the forecastle deck, bulwark gunwale, bulkhead (Both port and STBD side), brackets underneath and horizontal to gunwale and the hull, in general, are the areas of the mother vessel prone to contact damages caused by lighters situation worsens often because of the fact that generally the lighter vessel do not have winches fore and aft in order to heave up berthing ropes quickly. It is true that lightering at Chittagong outer anchorage during the period of yearly monsoon is difficult but it is only during some of seasonal the period. If adequate preventive measures are taken, collisions of nature under consideration can be avoided. However due consideration to the involved facts and circumstances leading to a particular incident are to be given. Usually the freeboard of a lighter vessel is much higher than that of the mother vessel when the former approach the latter the reason being that the lighter vessel is in light condition while the mother vessel is fully loaded to avoid contact damage in such in a situation a close communication/coordination between both the lighter and mother vessel involved are needed.

of the prevailing strong current at outer

a velocity of the current being 6 knots and
other marine factors.
